Ratings and reviews

Just installed. Very impressive on arrays and orientation. It would be good to have the capability of charging the battery at off peak hours, with an off-peak and day high rate. That would lead to estimates of smart usage of the grid in winter months, especially. Good to put in a battery but needs improvement. Also I would prefer to put in my kw demand to allow for heat pump use between times of the day. That all said 6 stars, but I would need to explore others, but this app has impressed me.

Excellent app, by far the best I've ever seen. It's an outstandingly powerful tool covering complex situations with flexible and customisable input as well as data analysis, whilst everything remains user-friendly, nicely organized, clearly understandable and visually attractive. This is exactly what I needed for designing my solar system and finding the best and the most optimized configuration among myriads of possibilities. Surprisingly, for such a value there are no in-app purchases nor ads.

Amazing app, it let you estimate the best position for PV, number of panels, inverter power and so on. Even if the free version doesn't allow combinations of panels and orientations it remains very good for an amateur.
